Title: Fabrication of semiconductor device
Inventor: KUSHIMA YUKIMOTO
IPC: H01L29/792
Filed: 1993-10-04
Abstract: PURPOSE:To prevent the quality of gate oxide from lowering after patterning by depositing a gate oxide, Si3N4, and a resist film on a semiconductor substrate, patterning the Si3N4 using the resist film as a mask, depositing a gate oxide using the Si3N4 as a mask, and then removing the Si3N4 film. CONSTITUTION:A gate oxide 2 is deposited on a semiconductor substrate 1, Si3N4 3 is deposited thereon, and a resist film 4 is further formed thereon. The S3,N4 3 is then patterned using the resist film 4 as a mask. Subsequently, the resist film 4 is removed and a gate oxide is formed using the patterned Si3N<4> 3 as a mask and then the Si3N4 3 is removed. Consequently, the resist film 4 does not come into direct contact with the gate oxide 2 during the process for depositing FG gate oxide in flash memory. This method prevents the quality of gate oxide from deteriorating due to thermal diffusion during the process following to the patterning of gate oxide 2.

Title: Cutter device
Inventor: IIJIMA TOMOMI
IPC: B26D1/09
Filed: 1993-10-04
Abstract: PURPOSE:To selectively carry out the full cut and stab cut by varying the shift stroke of a cutter by varying the turning angle quantity of a driving motor which is revolution-driven in the normal nd reverse directions by a reciprocating turn quantity control means. CONSTITUTION:When a full cut selection signal is inputted, a cutter swing body 10 turns in reciprocation by a set angle quantity theta1 for full cut, while if a stab cut selection signal is inputted, a driving motor 39 is drive-controlled by a reciprocating turn quantity control means so that the cutter swing body 10 performs reciprocating turn by the set angle quantity theta for stab cut. Accordingly, full cut and stab cut are carried out by varying the shift stroke of a cutter 2 by varying the turning angle quantity in the normal and reverse directions of the driving motor 39. Accordingly, the necessity of the large-sized parts such as stab magnet and lever is eliminated, and the number of parts can be reduced drastically.

Title: Diaphragm pump
Inventor: NUMATA KAZUYUKI
IPC: F04B43/02
Filed: 1993-08-27
Abstract: PURPOSE:To increase a discharging amount so as to improve pump efficiency while maintaining durability of a diaphragm type paint pump. CONSTITUTION:In a diaphragm type paint pump, a discharging amount or pump efficiency is increased as a diameter of a diaphragm pressing plate is increased, however, on the other hand, durability is reduced as a bending angle of the diaphragm in operation is increased. Therefore, a diaphragm 111 is pressed by two pressing plates 114, 115 with different diameters, so that places in which bending is generated on the diaphragm are distributed, and durability is improved while pump efficiency is improved. The pressing plate 115 on a driving chamber 113 side is formed larger than the pressing plate 114 on a pump chamber 112 side, and during the operation of liquid discharging action, the diaphragm 111 is pressed by the pressing plate 115 with a larger area so that waving in the diaphragm 111 is regulated, and consequently, the liquid discharging amount is stabilized.

Title: Double tub type washer
Inventor: OKAMOTO YOSHIMI
IPC: D06F41/00
Filed: 1989-09-25
Abstract: PURPOSE:To improve foam breaking and to heighten rinsing efficiency even when the stirring force of a washing blade is strengthened by generating a time cycle by a weak water flow with on-time shorter and off-time longer than an ordinary rinsing time cycle before completing injection rinsing wash by a wash timer. CONSTITUTION:The wash timer 2 having a main switch 9 to turn on and off a power source 1 is formed so as to be switched selectively with a weak inversion switch 5 and a strong inversion switch 6 via a water flow change over switch 3, and drives a capacitor-running type single-phase induction motor 8 by a capacitor with a time interval set with the weak inversion switch 5 and the strong inversion switch 6. A reference water flow can be generated with the strong inversion switch 6 via a switch 4 by aligning the water flow change-over switch 3 to continuous line side, however, since the switch 4 is set so as to be opened before the main switch 9 is turned off, a soft water flow can be obtained with the weak inversion switch 5. Therefore, it is possible to improve the foam breaking in the injection rinsing wash and to heighten the rinsing efficiency even when the stirring force of the washing blade is strengthened.

Title: Entire pressure contact type semiconductor device
Inventor: KANDA KAZUYOSHI
IPC: H01L21/52
Filed: 1985-11-08
Abstract: PURPOSE:To facilitate axial centering of a semiconductor substrate and a conductor by stably holding an insulating ring engaged with the conductor by utilizing the inner peripheral surface of a surface protecting material to become concentric circle with the conductor to prevent the substrate from radially moving. CONSTITUTION:Aluminum is deposited on both side main surfaces of a semiconductor substrate 1 to form metal electrodes 2. Since a P-N juinction is exposed on the outer peripheral end of the substrate 1, it is formed in a bevel shape to reduce an electric field of the surface, and a surface protecting material 7 is coated concentrically with the substrate 1. The electrode 2 is contacted under pressure with a pair of conductors 5, 6 through intermediate buffer plates 3, 4. In this case, the outer periphery of a ring-shaped insulator 8 having a predetermined thickness engaged with the conductor 6 and the inner periphery of a material 7 are contacted at a home position to fix the radial movement of the substrate 1, thereby facilitating the axial centering of the substrate 1 and the conductor 6.

Title: Production of highly corrosion resistant aluminized cr-containing steel sheet excellent in adhesive strength of plating
Inventor: TOMITA MINORU
IPC: C23C2/12
Filed: 1989-09-27
Abstract: PURPOSE:To obtain a highly corrosion resistant aluminized steel sheet excellent in adhesive strength of aluminizing layer by previously applying oxidation and reduction treatments to the surface of a steel sheet under respectively specified conditions at the time of applying hot dip aluminizing to the surface of a Cr-containing steel sheet. CONSTITUTION:A cold rolled sheet of Cr steel containing 10-25% Cr is depreased, annealed, pickled, ground, and then heated up to 400-600 deg.C in an oxidizing or weekly oxidizing atmosphere of 0.9-1.5 air ratio by means of a burner, by which a thin film of oxide composed essentially of Fe is formed on the surface of the steel sheet. Subsequently, heating is applied to the above steel sheet up to 700-950 deg.C in a reducing atmosphere to reduce the oxide on the steel-sheet surface, and then, a hot dip aluminizing layer is formed on the surface of the steel sheet by passing the steel sheet through a hot dip aluminizing bath while applying cooling to this steel sheet. Since the steel sheet itself contains Cr and has superior heat resistance and oxidation resistance and, further, the hot dip aluminizing layer is formed with superior adhesive strength, the aluminized steel sheet having high corrosion resistance can be obtained.

Filed: 1983-12-30
Abstract: PURPOSE:To reduce iron ore and to produce efficiently and directly molten iron by preheating iron ore and reducing preliminarily the iron ore with the waste gas from a melt reduction furnace then blowing the iron ore to the melt reduction furnace, blowing carbonaceous material and oxygen thereto and heating the iron bath. CONSTITUTION:Iron ore is preheated in a preheating furnace 1 and is fed into a preliminary reduction furnace 2 where the iron ore is subjected to reduction to some extent to decrease the content of iron oxide and thereafter the iron ore is bottom-blown together with a carbonaceous material, oxygen, slag forming agent, etc. through blow ports 4, 5 into a melt reduction furnace 3. Secondary oxygen is top-blown through a blow port 6 into the furnace to burn a part of the combustible gas generated by the gasification reaction of the carbonaceous material, thereby reducing the iron ore and heating the iron bath. The molten iron is thus obtd. The high-temp. gas formed in this stage is passed through a heat exchanger 8, by which heat is recovered. The gas is further mixed with part of the gas recovered from the furnace 2 and the geseous mixture is passed through a decarbonizing device 10 where the degree of oxidation of the gaseous mixture (H2O+CO2)/(H2+H2O+CO+CO2) is adjusted to 0.07-0.15. The gas is heated in a heater 11 and is introduced into the furnace 2 to make the preliminary reduction ratio therein 0.60-0.75.
